If you are looking for a fun game without paying a dime, look no further than Battleloot Adventure. The modern quest game with turn-based action scenes is dropping from 99 cents to $0 for the next 36-hours. The promotion is in conjunction with the myAppFree service, which makes deals with developers to temporarily drop the price of an app or game in an effort to gain visibility in the Store.
Battleloot Adventure "blends comedy, turn-based combat and role-playing for a whimsical adventure like no other!" but what I like about it is the endearing artwork, which has a hand drawn like charm.
